[0069] The embodiments of the present application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0070] Malocclusion is a common condition in children during their development and is caused by multiple factors. Invisible braces often require the use of jaw pads to raise the posterior teeth to correct an underbite or reconstruct the occlusion. Traditional jaw pads can be formed on the surface of the appliance as a cavity or filled cavity (the filling can be fixed to the teeth or detached), or a jaw pad can be bonded to the outside of the appliance. Most jaw pads have a fixed shape, while a few take into account the cusp structure of the opposing teeth, with their surfaces designed to match the opposing teeth to better achieve locking of the upper and lower jaws. Current jaw pad designs are based on the bite record obtained through oral scans or silicone gel to determine the positional relationship between the upper and lower jaws. However, this upper and lower jaw relationship may not necessarily meet the treatment objectives in some treatments, especially in some delicate jaw position designs, which lack the ability to precisely adjust the jaw position through further design and control of the jaw pad height and surface inclination. The essence of a jaw pad is to form a specific raised structure on the teeth or orthodontic appliances, thereby changing the occlusal relationship between the upper and lower jaws, forming a jaw position adjustment treatment, providing a spatial channel for orthodontic treatment, or by changing the occlusal state of the teeth, the bite force acts on specific teeth to lower the teeth.

[0071] The current jaw pads are designed based on the occlusal records obtained by oral scanning or silicone using a clinical appliance to determine the positional relationship between the upper and lower jaws. However, this upper and lower jaw relationship may not necessarily meet the treatment objectives in some treatments. In particular, in some sophisticated jaw position designs, there is a lack of the ability to precisely adjust the jaw position through further design and control of the jaw pad height and surface inclination.

[0072] These fine adjustments often cannot be determined simply by relying on the positional relationship between the upper and lower jaws, as determined by bite records obtained through oral scans or silicone before clinical treatment. Instead, further design is required based on this foundation. By adjusting the height, surface slope, and shape of the jaw pad along the dental arch, a specific relationship between the upper and lower jaw positions, occlusion, and bite force is established. Based on the clinical jaw position, the distribution of the jaw pad height and surface slope along the dental arch is controlled to create a jaw pad with directional adjustment capabilities.

[0073] This embodiment provides a dental appliance assembly, a determination method, a display method, an apparatus and an electronic device, and a storage medium. The dental appliance assembly with an occlusal structure or an integrated occlusal structure used has at least one change in height, shape, and surface slope along the direction of the dental arch, thereby giving the occlusal structure a directional adjustment function. On the basis of the existing jaw pad, the jaw pad's ability to accurately adjust the jaw position and occlusal relationship is further improved.

[0074] As shown in FIG1 , this embodiment provides a method for determining a dental appliance assembly, which includes:

[0075] S1: Obtain the patient's first maxillomandibular relationship.

[0076] S2: Determine a dental appliance assembly based on the first maxillomandibular relationship, where the dental appliance assembly includes an occlusal structure, and a second maxillomandibular relationship formed by the occlusal structure in the first direction is different from the first maxillomandibular relationship.

[0077] In one embodiment, the dental appliance assembly includes an appliance body and an occlusal structure located on an occlusal surface of the appliance body, wherein the occlusal structure and the opposing jaw abut against each other to form a second maxillomandibular relationship.

[0078] In the present application, the first maxillomandibular relationship may be a maxillomandibular relationship with no specified jaw position, or a maxillomandibular relationship with a specified jaw position.

[0079] In a possible implementation, the first maxillomandibular relationship can be obtained through an oral model acquisition method such as three-dimensional oral scanning or occlusal silicone mold model recording.

[0080] In a possible implementation, the first maxillomandibular relationship may be a maxillomandibular position relationship specified by a doctor based on an oral model of the patient and pulled by the patient's muscle movements or fixed by auxiliary measures.

[0081] In a possible implementation, the first maxillary and mandibular relationship may also be a positional relationship manually adjusted using virtual models of the maxillary and mandibular in a virtual environment such as a computer.

[0082] In another possible implementation, the first maxillomandibular relationship may also be a maxillomandibular relationship obtained by simulation based on a software algorithm.

[0083] Considering that medical treatment plans, especially oral treatment plans such as orthognathic orthodontics, may comprehensively consider factors such as the patient's oral structure, the type and degree of malocclusion, and the patient's individual oral physiological characteristics, therefore, for some patients, the primary maxillomandibular relationship may not necessarily meet the treatment purpose in certain medical treatments, especially in some sophisticated jaw position designs, which require precise adjustment of the jaw position.

[0084] In some embodiments, the second maxillomandibular relationship may be the maxillomandibular position relationship expected to be obtained by adjusting the first maxillomandibular relationship during the correction process.

[0085] One possible implementation method is to obtain a second maxillomandibular relationship based on the adjustment of the occlusal structure in the first direction.

[0086] In a possible implementation, the first direction includes: one or more of: along the dental arch direction, sagittal direction, vertical direction, and horizontal direction.

[0087] In a specific implementation process, there are multiple ways to change the occlusal structure in the first direction to achieve the second occlusal relationship.

[0088] In a possible implementation, the surface of the occlusal structure has at least one of a height, a shape, and a surface slope that changes along the dental arch direction.

[0089] In a possible implementation, the slope distribution includes: the left jaw and the right jaw have the same horizontal inclination.

[0090] In one possible implementation, the surface of the occlusal structure includes at least one of the following:

[0091] At least partially continuous distribution; at least partially discrete distribution; at least partially linear distribution; at least partially nonlinear distribution.

[0092] In one possible implementation, the occlusal structure has a higher height along the dental arch direction, at least in part, as it approaches the posterior tooth side; or the occlusal structure has a lower height along the dental arch direction, at least in part, as it approaches the posterior tooth side.

[0093] In a possible implementation, the first direction includes one or more of: along the dental arch direction, sagittal direction, vertical direction, and horizontal direction.

[0094] In a possible implementation, the height of the engaging structure ranges from 0.5 to 1 mm.

[0095] In a possible implementation, the height variation of the occlusal structure satisfies: 0.5-1 mm.

[0096] Optionally, the second maxillomandibular relationship may be slightly different from the first maxillomandibular relationship, for example, there is no difference on tooth No. 4, but a difference of 1 mm on tooth No. 7.

[0097] In a possible implementation, the occlusal structure is arranged along the dental arch direction and covers at least one tooth.

[0098] In a possible implementation, the occlusal structure is provided on the left jaw and the right jaw.

[0099] In one possible implementation, the occlusal structure may be an accessory added to the appliance body, or may be a structure used in conjunction with the appliance body in the form of a jaw pad, jaw plate, etc.

[0100] The following uses a jaw pad as an example to illustrate the occlusal structure of the present application.

[0101] In a possible implementation, the surface of the occlusal structure may include a change in at least one of height, shape, and surface slope along the dental arch direction, wherein the height is the height along the vertical direction.

[0102] One possible implementation involves designing a further precisely adjusted second maxillomandibular relationship based on the first maxillomandibular relationship. This second maxillomandibular relationship adjusts jaw position and occlusion relative to the first, or creates a different bite force between the upper and lower jaws than in the first maxillomandibular relationship, achieving specific treatment goals. This second maxillomandibular relationship can better meet the individual needs of different patients, allowing for more precise treatment plans and improved treatment outcomes.

[0103] In a possible implementation, in terms of positional relationship, there may be the following multiple situations between the second maxillomandibular relationship and the first maxillomandibular relationship.

[0104] In a possible implementation, in the side view direction, the jaw plane of the second maxillomandibular relationship rotates clockwise or counterclockwise relative to the jaw plane of the first maxillomandibular relationship.

[0105] In a possible implementation, in the front view direction, the jaw plane of the second maxillomandibular relationship rotates clockwise or counterclockwise relative to the jaw plane of the first maxillomandibular relationship.

[0106] In a possible implementation, in the jaw plane viewing direction, the jaw plane of the second maxillomandibular relationship rotates clockwise or counterclockwise relative to the jaw plane of the first maxillomandibular relationship.

[0107] In a possible implementation, in the jaw plane view direction, the jaw plane of the second maxillomandibular relationship is translated and offset relative to the jaw plane of the first maxillomandibular relationship in at least one of the sagittal direction, the vertical direction, and the horizontal direction.

[0108] In a possible implementation, in addition to the above-mentioned positional relationship, the second maxillomandibular relationship may also include other positional relationships obtained by further adjusting the first maxillomandibular relationship.

[0109] In one possible implementation, the position of the second maxillomandibular relationship relative to the first maxillomandibular relationship can be flexibly adjusted according to different patient conditions and different medical treatment purposes.

[0110] One possible implementation method is to adjust the surface of the occlusal structure to have at least one change in height, shape, and surface slope along the dental arch direction, so that the occlusal structure forms a structure that at least partially has a height change trend, thereby utilizing the change in the height and / or surface slope of the occlusal structure to enable the first maxillary and mandibular relationship to be adjusted to the second maxillary and mandibular relationship, forming an adjusted maxillary and mandibular position relationship, occlusal relationship, or occlusal force relationship, where the height is the height along the vertical direction.

[0111] In one possible implementation, the change in the occlusal structure includes at least one of height, shape, and surface slope along the dental arch. For example, the occlusal structure may be at least partially continuously distributed or at least partially discretely distributed; or at least one of the height, shape, and surface slope of the occlusal structure along the dental arch may be adjusted to form at least a partially linear distribution or at least a partially nonlinear distribution, with the height being the height along the vertical direction.

[0112] In one possible implementation, when the occlusal structure is at least partially continuously distributed, the occlusal structure adjustment is applied to the dental arch in an at least partially continuous manner, forming at least partially smooth height changes. This is suitable for situations where gradual adjustment is required, thereby achieving a more natural and gradual jaw position change. When the occlusal structure is at least partially discretely distributed, the occlusal structure adjustment is performed in units of at least partially discrete points or areas, forming at least partially discontinuous height changes. This is suitable for situations including concentrated adjustment of specific areas, thereby achieving localized adjustment of the teeth.

[0113] In one possible implementation, when the engagement structure is at least partially linearly distributed, the engagement structure may be increased or decreased at least partially uniformly or at least partially in a specific ratio, which is applicable to situations where uniform adjustment is required.

[0114] One possible implementation method is that when the occlusal structure is at least partially nonlinear, it can be adjusted more flexibly according to the needs of specific teeth or areas, which is suitable for situations that require personalized and differentiated adjustments and is closer to the actual condition of the patient's oral cavity.

[0115] One possible implementation method is to adjust the occlusal structure so that at least part of it is higher along the dental arch as it approaches the posterior teeth; or to adjust the occlusal structure so that at least part of it is lower along the dental arch as it approaches the posterior teeth.

[0116] In one possible implementation, the overall height change trend of the occlusal structure is at least partially continuous, thereby effectively balancing the occlusal force and accurately controlling the jaw position.

[0117] In one possible implementation, the occlusal structure can be installed on the left jaw, the right jaw, or both jaws, depending on the patient's condition; or on the mandible, the maxilla, or both jaws. The size and range can be adjusted based on actual needs and are not limited here.

[0118] In one possible implementation, the occlusal structures of the left and right jaws may have the same horizontal inclination according to the conditions of different patients, or different inclinations may be set for the left and right jaws, respectively.

[0119] In one possible implementation, the occlusal structure is arranged along the dental arch and covers a range of one tooth or more. Alternatively, the occlusal structure is arranged along the dental arch and can cover a range of teeth 4 to 7. Of course, the occlusal structure can also be a discrete structure, with only a portion of the tooth area being arranged, thereby achieving a precise control effect.

[0120] There are many ways to arrange the occlusal structure on the orthodontic appliance body.

[0121] One possible implementation method is to form a raised cavity structure or solid structure on the orthodontic appliance body with at least one change in height, shape and surface slope along the dental arch direction, so that the cavity structure or solid structure constitutes an occlusal structure, and the height is the height along the vertical direction.

[0122] In one possible implementation, an occlusal structure is fixed on the upper surface of the appliance body, and the surface of the occlusal structure has at least one change in height, shape, and surface slope along the dental arch direction, and the height is the height along the vertical direction.

[0123] In one possible implementation, the occlusal structure may be integrated into the appliance body or be an additionally provided occlusal structure.

[0124] One possible implementation involves creating a hollow structure, which can reduce weight and improve wearer comfort. Alternatively, the cavity can be filled with a solid material, such as a light-curable resin or gel, to increase structural strength and ensure adequate stability and support.

[0125] In a possible implementation, when the interlocking structure is an additional configuration, its material may also be a light-curing resin, gel, etc., and may also be a solid structure or a cavity structure.

[0126] This embodiment also provides an occlusal structure, the surface of which has at least one change in height, shape and surface slope along the direction of the dental arch. When the occlusal structure is set on the orthodontic appliance body, the outer surface of the orthodontic appliance / tooth is in contact with each other, forming a second maxillary and maxillary relationship that is different from the first maxillary and maxillary relationship, and the height is the height along the vertical direction.

[0127] In one possible implementation method, the first maxillomandibular relationship is a specified maxillomandibular position relationship obtained by traction of the patient's muscle movement or fixed by auxiliary measures, or is a maxillomandibular position relationship obtained by manual adjustment based on a virtual model, and the second maxillomandibular relationship is the maxillomandibular position relationship expected to be adjusted based on the first maxillomandibular relationship during the correction process.

[0128] In a possible implementation manner, the interlocking structure forms an at least partially continuous distribution or an at least partially discrete distribution; or forms an at least partially linear distribution or an at least partially nonlinear distribution.

[0129] In one possible implementation, the height of the occlusal structure increases along the dental arch direction, closer to the posterior teeth.

[0130] In one possible implementation, the height of the occlusal structure decreases along the dental arch direction as it approaches the posterior tooth side.

[0131] In one possible implementation, the occlusal structure covers the range of teeth 4 to 7.

[0132] In a possible implementation, the occlusal structure is a solid or hollow structure.

[0133] In one possible implementation, the surface of the occlusal structure is provided with at least partially continuously distributed microstructures, such as different types of lines, grooves, protrusions and other microstructural features, thereby increasing the friction of the surface of the occlusal structure.

[0134] This embodiment also provides a dental brace assembly, which includes an appliance body. A raised cavity structure or solid structure with at least one of height, shape, and surface slope changes along the dental arch direction is formed on the occlusal surface of the appliance body. The cavity structure or solid structure constitutes an occlusal structure. When the occlusal structure and the outer surface of the opposing jaw appliance / tooth are in contact with each other, a second maxillary and mandibular relationship that is different from the first maxillary and mandibular relationship is formed.

[0135] In one possible implementation method, the first maxillomandibular relationship is a specified maxillomandibular position relationship obtained by traction of the patient's muscle movement or fixed by auxiliary measures, or is a maxillomandibular position relationship obtained by manual adjustment based on a virtual model, and the second maxillomandibular relationship is the maxillomandibular position relationship expected to be adjusted based on the first maxillomandibular relationship during the correction process.

[0136] In a possible implementation manner, the interlocking structure forms an at least partially continuous distribution or an at least partially discrete distribution; or forms an at least partially linear distribution or an at least partially nonlinear distribution.

[0137] One possible implementation is that when the occlusal structure is at least partially linearly distributed on the appliance body, the occlusal structure is higher along the dental arch direction as it is closer to the posterior tooth side, or lower along the dental arch direction as it is closer to the posterior tooth side.

[0138] In one possible implementation, the occlusal structure is formed in the range of teeth 4 to 7 of the orthodontic appliance body.

[0139] In a possible implementation, a filler is provided in the cavity structure of the occlusal structure.

[0140] In one possible implementation, the surface of the engaging structure is provided with at least partially continuously distributed microstructures.

[0141] This embodiment also provides a dental brace assembly, including a first brace and a second brace arranged on opposite jaw sides, the first brace including an brace body and an occlusal structure located on the occlusal surface of the brace body, the occlusal structure is used to adjust the relative position relationship between the upper and lower jaws, the contact surface of the occlusal structure and the second brace is different in at least one of the height, shape and surface inclination in a first direction, and the first direction is one or more of the following directions: along the dental arch direction, sagittal direction, vertical direction and horizontal direction.

[0156] In a possible implementation, the first direction includes: one or more of: along the dental arch direction, sagittal direction, vertical direction, and horizontal direction.

[0157] In a possible implementation, the surface of the occlusal structure has at least one of a height, a shape, and a surface slope that changes along the dental arch direction, and the height is the height along the vertical direction.

[0169] In one possible implementation, the occlusal structure is fixed to the occlusal surface of the appliance body, or is integrally formed with the appliance body.

[0170] In one possible implementation, at least a portion of the surface of the engaging structure includes: at least partially continuously distributed microstructures.

[0171] The present embodiment will be further described below with reference to several examples.

[0172] As shown in Figures 2a and 2b, Figure 2a shows the first maxillomandibular relationship obtained by clinical molding, and Figure 2b shows the second maxillomandibular relationship after adjustment. When designing the jaw pad, a jaw pad is set on the mandibular posterior teeth according to the first maxillomandibular relationship, so that the upper and lower jaws are consistent with the first maxillomandibular relationship after occlusion. However, in actual medical treatment, the doctor may want to lower the posterior teeth more, but does not want the bite force to be concentrated only on the terminal molars. By setting the occlusal structure 1, the height distribution along the dental arch is higher towards the posterior teeth, and the change is usually controlled in the range of 0.5~1mm. This allows the posterior teeth to be subjected to a greater bite force, but under the action of the bite force, the premolars can also bear a certain bite force through the slight deformation of the appliance body.

[0173] Optionally, assuming that the correction goal is to lower the terminal molars, the height of the occlusal structure 1 at the terminal molar position is higher than the height at other teeth (such as premolars), so that the occlusal structure 1 exerts a greater occlusal force on the terminal molars.

[0174] As shown in Figures 3a and 3b, Figure 3a shows the first maxillomandibular relationship obtained from clinical impressions, and Figure 3b shows the second maxillomandibular relationship after adjustment. The surgeon may wish to reduce the forces on the molars to allow for their elongation. By adjusting the occlusal structure 1, the height distribution along the dental arch decreases toward the posterior teeth. The adjustment is typically controlled within a range of 0.5 to 1 mm. This reduces the forces on the posterior teeth and may even create a slight gap between the opposing jaws.

[0175] Optionally, assuming that the correction goal is to lengthen the molars, the height of the occlusal structure 1 at the molars is lower than that at other teeth (such as the front teeth), so that the occlusal structure 1 does not hinder the elongation of the molars.

[0176] As shown in FIG4 , the occlusal state is changed by changing the thickness of the appliance body 2 along the dental arch direction to form a second maxillary and mandibular relationship, and the thickened entity structure can be segmented or gradually changed.

[0177] Optionally, the thickness of the diaphragm in the first area of ​​the appliance body 2 is greater than the thickness of the diaphragms in other areas. In this case, the first area of ​​the appliance body 2 can be regarded as an occlusal structure.

[0178] As shown in FIG5 , a second maxillomandibular relationship is formed by forming a cavity protrusion on the appliance body 2 and utilizing the height change of the protrusion structure to change the occlusal state.

[0179] As shown in FIG6 , the occlusal structure formed on the appliance body 2 is a plurality of discontinuous protrusion structures.

[0180] In Figure 6, the horizontal inclinations of the occlusal structures on the left and right jaws differ, tilting the jaw plane between the upper and lower jaws. This effectively corrects misalignment or produces the desired bite force. In this case, the maxillary plane in the front view rotates counterclockwise. Alternatively, misalignment can be corrected or the desired bite force can be produced by varying the height of the upper jaw extensions on the left and right hemimaxilla.

[0181] The present invention provides a method for jaw adjustment using a dental appliance assembly, the dental appliance assembly including an appliance body, wherein a first upper and lower jaw relationship is obtained according to a doctor's instruction; a height variable body is provided on the appliance body; and the height, shape, and surface slope distribution of the height variable body along the dental arch are adjusted so that when the outer surface of the dental appliance assembly and the outer surface of the opposing appliance / teeth abut against each other, a second upper and lower jaw relationship different from the first upper and lower jaw relationship is formed.

[0182] One possible implementation method is a variable height body, which can be a change in the local thickness of the appliance body, a raised cavity structure on the surface of the appliance body (the cavity can be filled with a solid material, such as light-curing resin, gel, etc.), or a solid / cavity jaw pad fixed on the surface of the appliance body (such as light-curing resin, gel, etc.).

[0183] In a possible implementation, the distribution of the height, shape and surface slope of the variable height body along the dental arch direction may be discrete or continuous; such distribution may be linear or nonlinear.

[0184] In a possible implementation, the linear distribution may be such that the height of the body increases toward the posterior teeth along the dental arch, or decreases toward the posterior teeth along the dental arch.

[0185] One possible implementation, the slope distribution, may be that the left and right jaws have the same horizontal inclination.

[0186] A possible implementation method is that the jaw plane of the second upper and lower mandibular relationship, relative to the jaw plane of the first upper and lower mandibular relationship, has clockwise and counterclockwise rotation in the right view; clockwise and counterclockwise rotation in the front view; clockwise and counterclockwise rotation in the jaw plane view; and translation offset in the sagittal direction, vertical direction, and horizontal direction.

[0187] One possible implementation method is that the second upper and lower jaw relationship allows for a directionally adjusted jaw position and occlusal relationship based on the first upper and lower jaw relationship; it can also allow the upper and lower jaws to produce a tooth occlusal force that is different from that of the first upper and lower jaw relationship, thereby achieving a specific corrective effect.

[0188] In a possible implementation, the second maxillary-mandibular relationship may be slightly different from the first maxillary-mandibular relationship, for example, there is no difference on tooth No. 4, but a difference of 1 mm on tooth No. 7.

[0189] In a possible implementation, the variable height body is arranged along the dental arch direction and covers a range greater than or equal to 1 tooth; in particular, covers the range of teeth 4 to 7; the variable height body can be adjusted to not be set on some of the teeth.

[0190] In a possible implementation, the variable height body described in is set on the left jaw or the right jaw; the variable height body described in 1 is set on the lower jaw, the upper jaw, or both the upper and lower jaws.

[0191] In a possible implementation, the first upper and lower jaw relationship described above can be obtained by methods such as oral scanning and biting a silicone mold.

[0192] In one possible implementation, the first upper and lower jaw relationship described above can be a certain upper and lower jaw relationship specified by a doctor and fixed by the patient's muscle movement or auxiliary measures; or it can be a positional relationship manually adjusted using a virtual model of the upper and lower jaw in a virtual environment such as a computer.

[0193] In a possible implementation, the variable height body on the maxillary surface and dental arch may be a discrete design or an integral design or a combination of the two.

[0194] In a possible implementation, the surface of the variable height body may be provided with various types of microstructure features such as lines, grooves, protrusions, etc., to increase the mutual friction without changing the relationship between the second upper and lower jaws.

[0195] A possible implementation method is to use the above method to form a dental appliance component variable height body and a dental appliance component.

[0196] To sum up, this embodiment provides an occlusal structure with varying height, shape or surface slope along the dental arch direction, thereby giving the occlusal structure a directional adjustment function. On the basis of the existing jaw pad, the jaw pad's ability to precisely adjust the jaw position and occlusal relationship is further improved.
